Actually chadhill there is a version mismatch in the DOE extensions.
More core is version 1.38 (or close) but the extension is requesting a minrelease of 12...
I thought Dulux_Oz had fixed so Ill ping him again...

You can change each of the extensions or just for now you can change the one line in MoreCores base.xml from

<root version="3.0" release="1.38" logo="logo.png">

to

<root version="3.0" release="12" logo="logo.png">
